I just boost from 10-40 and do a little zf for teh quest then just quest to 60.

1-10 is 1.5 hours
10-20 is 2 hours in SFK
20-40 is 5 hours sfk/SM

my last group I got up to 60 in 1 day and 3 hours, the on before was 1 day 11 hours, the more you do it the faster it gets. I think before RAF i got one guy up to 60 in a little over 3 days.
